How Push-To-Talk Makes Talk Less Pushy

This paper presents an exploratory study of college-age students using two-way, push-to-talk cellular radios. We describe the observed and reported use of cellular radio by the participants. We discuss how the half-duplex, lightweight cellular radio communication was associated with reduced interactional commitment, which meant the cellular radios could be used for a wide range of conversation styles. One such style, intermittent conversation, is characterized by response delays. Intermittent conversation is surprising in an audio medium, since it is typically associated with textual media such as instant messaging. We present design implications of our findings.Comment: 10 page

Making Space for Stories: Ambiguity in the Design of Personal Communication Systems

Pervasive personal communication technologies offer the potential for important social benefits for individual users, but also the potential for significant social difficulties and costs. In research on face-to-face social interaction, ambiguity is often identified as an important resource for resolving social difficulties. In this paper, we discuss two design cases of personal communication systems, one based on fieldwork of a commercial system and another based on an unrealized design concept. The cases illustrate how user behavior concerning a particular social difficulty, unexplained unresponsiveness, can be influenced by technological issues that result in interactional ambiguity. The cases also highlight the need to balance the utility of ambiguity against the utility of usability and communicative clarity.Comment: 10 page

Detecting User Engagement in Everyday Conversations

This paper presents a novel application of speech emotion recognition: estimation of the level of conversational engagement between users of a voice communication system. We begin by using machine learning techniques, such as the support vector machine (SVM), to classify users' emotions as expressed in individual utterances. However, this alone fails to model the temporal and interactive aspects of conversational engagement. We therefore propose the use of a multilevel structure based on coupled hidden Markov models (HMM) to estimate engagement levels in continuous natural speech. The first level is comprised of SVM-based classifiers that recognize emotional states, which could be (e.g.) discrete emotion types or arousal/valence levels. A high-level HMM then uses these emotional states as input, estimating users' engagement in conversation by decoding the internal states of the HMM. We report experimental results obtained by applying our algorithms to the LDC Emotional Prosody and CallFriend speech corpora.Comment: 4 pages (A4), 1 figure (EPS

Affectivism about intuitions

This article provides an account of intuitions: Affectivism. Affectivism states that intuitions are emotional experiences. The article proceeds as follows: first, the features that intuitions are typically taken to have are introduced. Then some issues with extant theories are outlined. After that, emotional experiences and their central features are brought into view. This is followed by a comparison of intuitions and emotional experiences, yielding the result that emotional experiences fit and elucidate the feature profile of intuitions. Finally, it is specified what kind of emotional experiences intuitions are: intuitions are typically mild emotional experiences that belong to the subclass of epistemic feelings

Advice giving in telephone interactions between mothers and their young adult daughters

This thesis focuses on the social organisation of advice, as it unfolds in interactions between mothers and their young adult daughters on the telephone. The analysis is based on a corpus of 51 telephone calls from 5 different families. Advice giving is studied here using the methods of conversation analysis and discursive psychology. The main interest has been to consider the dimensions that are relevant to the potentially tricky action of advice giving, building on the dimensions of normativity and knowledge asymmetry that have already been identified in the literature. The less strictly institutionalised context studied here provides a relatively new arena for considering the array of issues that are relevant to advice giving. Indeed, this has provided a broad scope for specifying how recipiency is brought off in advice giving sequences and how the position of advice recipient is managed. The analysis begins by considering the different forms of advice that were found in the data and their affordances in terms of the recipient s next turn. Contingency is identified as an important dimension in advice giving and a range of resources are identified which build contingency into the advice in various ways and which provide the recipient with different degrees of optionality when responding to advice. The thesis then goes on to consider how recipients respond to advice and the sorts of issues that make relevant one response type over another. The analysis identifies the importance of affiliation and alignment when considering different types of advice response. Furthermore, it is shown that morality, activity type, and alignment to the recipient s position, are important features of why a particular response type is chosen over another. The final analytic chapter then considers how the potentially tricky action of advice giving is made relevant in the first place. It is shown that the choice between different forms of advice is related to local issues of entitlement and contingency. In considering these different components to advice giving, the analysis explicates an array of important issues in advice giving sequences including: knowledge asymmetry, normativity, entitlement, contingency, affiliation, alignment and morality as well as considering evidence to suggest that advice is a dispreferred action. The findings are discussed in terms of their implications for studying advice and promoting advice acceptance, as well as considering how we can begin to see relationality being constituted
